TITLE:
myEvent Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA19680

VERIFY ADVISORY:
http://secunia.com/advisories/19680/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
myEvent 1.x
http://secunia.com/product/9376/

DESCRIPTION:
Some vulnerabilities have been discovered in myEvent, which can be
exploited by malicious users to conduct script insertion and SQL
injection attacks, and by malicious people to compromise a vulnerable
system.

1) Input passed to the "event_desc" parameter in addevent.php is not
properly sanitised before being used. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site when a malicious event is viewed.

2) Input passed to the "event_id" parameter in addevent.php and
del.php, and to the "event_desc" in addevent.php is not properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "myevent_path" parameter in myevent.php and
initialize.php is not properly verified before being used to include
files. This can be exploited to execute arbitrary PHP code by
including PHP files from local or external resources.

4) Input passed to the "myevent_path" parameter is also not properly
verified in event.php and viewevent.php before being used to include
files. This can be exploited to execute arbitrary PHP code by
including PHP files from local or external resources.

Successful exploitation requires that "register_globals" is enabled
and "magic_quotes_gpc" is disabled.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
